What's a good Android app for quickly scanning QR codes and barcodes directly from my phone's home screen without having to open the app itself every time?

Okay, so I've been messing around with QR & Barcode Scanner Launcher, and the thing that stood out to me is how quickly you can get to the scanner. As a developer, I appreciate efficiency. Instead of opening the app and then selecting 'scan,' you can add a widget to your home screen that launches the scanner directly. It's a small thing, but it saves a few seconds each time, which adds up if you're scanning a lot of codes. The app itself is straightforward, does what it says on the tin, and the widget functionality is a definite plus for frequent users. It's pretty lightweight too, so it's not gonna hog resources or drain your battery, which is always a concern. I think it's a solid option if you need quick access to QR and barcode scanning.
